A BBC presentation where the climbing frame makes itself into various shapes - a cube, triangular prism, square-based pyramid and a regular tetrahedron. The clip describes the properties of the shapes.

A good game for introducing the concept of areas of rectangles. You need to either estimate how many squares cover the rectangles or you can test out for yourself dragging and dropping squares in place.

This interactive teaching tool can be used in a variety of mathematical contexts such as multiplication arrays, finding different shapes with the same area, nets and more. It is useful because there are different backgrounds such as dots.
